Comment 74 for bug 1873895

It happened to me as well on my lenovo ideapad laptop when I upgraded from Xubuntu 19.10 to 20.04, and my 1366x768 resolution ended all garbled. Then, after a while googling for solutions (which there wew so few!), I came up with a weird but functional workaround: I opened the display window, selected the 1366x768 resolution, rotation: inverted and reflection: horizontal and vertical, then applied. Worked!
